본 발명은 열가소성 수지시트의 시일방법 및 장치에 관한 것으로 예를 들어 식품, 일용품, 의약품등을 포장힉 위하여 쓰이는 블리스터(Blister)포장에 이용할 수가 있다. 열가소성 수지시트에 포장하여야 할 상품의 형상에 맞추어진 포켓(pocket)을 형성하고, 그 안에 의약품등의 내용물을 수용한후 A1박등의 대지로 시일한 블리스터 포장(PTP 포장)이 구라파에서 생겨, 일본에서도 1960년 전반에서부터 사용되게 되었다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sealing method and apparatus for a thermoplastic resin sheet, and can be used, for example, for blister packaging used for packaging food, daily necessities, and medicines. A blister package (PTP package) formed in Europe is formed in a thermoplastic resin sheet by forming a pocket in accordance with the shape of the product to be packaged, and containing the contents of medicines therein, and then sealed with earth such as A1 night. It was used in Japan in the early 1960s.

블리스터 포장에서의 종전의 시일공정에서는 시일판 또는 시일로울이 사용되고 있다.In a conventional sealing process in blister packaging, a seal plate or a seal roll is used.

제16도에 보여주는대로 시일판(61)을 사용한 시일공정인 경우, 도시않은 포켓이 형성된 열가소성 수지시트(62)는 시일받이판(63)에 보내지고, 여기서 송출로울(64)에서부터 공급된 A1 박등의 대지(65)가 시일판(61)에 의하여 시트(62)에 밀봉된다.In the case of the sealing process using the seal plate 61 as shown in FIG. 16, the thermoplastic resin sheet 62 with the pocket (not shown) is sent to the seal receiving plate 63, where A1 supplied from the feeding roll 64 is provided. The base 65 such as foil is sealed to the sheet 62 by the seal plate 61.

제17도에 보여주는대로 이러한 시일판(61)은 그 표면에 마름모눈 모양의 철 모양부(66)가 형성되고, 이러한 철 모양부(66)에 의하여 시트(62)와 대지(65)와의 시일부분에 마름모눈모양시일이 형성된다.As shown in FIG. 17, the seal plate 61 has a diamond-shaped iron portion 66 formed on the surface thereof, and the iron plate 66 seals the sheet 62 with the earth 65. As shown in FIG. A rhombic seal is formed in the part.

또한 제18도에 보여주는대로 시일로울을 사용한 시일공정인 경우, 포켓이 형성된 열가소성 수지시트(51)는 시일받이로울(52)에 보내져 여기서 송출로울 (53)에서 공급된 대지(54)가 시일로울(55)에 의하여 시트(51)에 시일된다.In addition, in the case of the sealing process using the seal roll as shown in FIG. 18, the thermoplastic resin sheet 51 having the pocket is sent to the seal receiving bowl 52, where the land 54 supplied from the feeding roll 53 is sealed. The sheet 51 is sealed by the sheet 51.

제19도에 보여주는대로 이러한 시일로울(55)은 그 표면에 마름모눈모양의 철 모양부(56)가 형성되고, 이러한 철 모양부(56)에 의하여 시트(51)와 대지(54)와의 시일부분에 마름모눈모양시일이 형성된다.As shown in FIG. 19, the seal roll 55 has a diamond-shaped iron portion 56 formed on a surface thereof, and the iron portion 56 seals the sheet 51 with the earth 54. As shown in FIG. A rhombic seal is formed in the part.

양자를 비교한 경우, 시일판(61)에 의하면, 큰 시일압과 높은 평면정밀도가 요구되어 또한 기다란 시일시간이 필요하기 때문에 근년이들을 필요로 하지 않는 시일로울(55)이 주류가 되고 있다. 상기한 종전의 시일로울(55)을 사용한 시일방법에 의하면 포장 재료로서 특히 폴리프로필렌(PP)시트를 사용하고 시일폭의 확대 및 고속성형을 도모할려고 하는데 다음과 같은 문제가 생겼다. 즉 대지(54)의 시트로의 먹혀들어가는 불량과 먹혀들어가는 불균형 발생, 이들에 동반한 시일강도의 저하와 시일강도의 불균형 발생등이다.In the case of comparing the two, the seal plate 61 is mainstream of the seal roller 55 which does not require the recent years because a large seal pressure and a high plane precision are required and a long seal time is required. According to the conventional sealing method using the seal roll 55, a polypropylene (PP) sheet is used as the packaging material, and the seal width is expanded and high-speed molding is attempted. In other words, poor feed to the sheet of the earth 54 and the resulting imbalance, the decrease in the seal strength and the imbalance of the seal strength accompanying them.

이들 문제를 해결하기위하여 종전에 ①시일온도를 올림, ②시일압력을 올림, ③마름모눈모양 철 모양부(56)의 형상을 변경한다. ④A1의 시일기재필름(A1 박시랜트(sealant))를 개량하여 양호한 시일성을 부여함,등의 개선책을 도모하고 있었다.In order to solve these problems, (1) raising the seal temperature (1), (2) raising the seal pressure (3), and (3) changing the shape of the diamond-shaped iron portion (56). (4) A1 sealant film (A1 thin sealant) was improved to provide good sealing properties, and to improve such measures.

그러나 ①에 의하면, 발연, 타붙음, 내용물의 변질이 생김, ②③에 의하면, 핀홀이 생기여 A1박의 균열이 생기고, 또한 ④에 의하면 PP의 시일온도를 180℃정도까지 낮게 할 수가 있으나, 시일눈의 먹어들어감은 외관상 만족할 수 있는 것은 아님.However, according to ①, fuming, sticking, and deterioration of the contents are generated. ② According to ② ③, pinholes are generated to cause cracking of the A1 foil, and according to ④, the sealing temperature of PP can be lowered to about 180 ° C. Ingestion of eyes is not satisfactory in appearance.

본 발명은 저온 고속의 조건으로 양호한 시일이 가능한 열가소성 수지시트의 시일방법 및 장치를 제공하는 것을 목적으로 한다.An object of the present invention is to provide a sealing method and apparatus for a thermoplastic resin sheet capable of good sealing under conditions of low temperature and high speed.

본 발명에서의 열가소성 수지시트의 시일방법은 포켓이 형성된 열가소성 수지시트에 시일부재를 사용하여 대지를 시일하는 열가소성 수지시트의 시일방법에서 평행인 홈이 형성된 홈부를 적어도 하나 갖는 제1의 시일부재에 의한 시일공정과 홈부의 홈이 상기한 제1의 시일부재의 홈부의 홈과 교차하도록 형성된 제2의 시일부재에 의한 시일공정을 갖고, 상기한 제1 및 제2의 시일부재에 의한 시일공정이 각각 적어도 1회 시행되는 것을 특징으로 하고 있다.In the sealing method of the thermoplastic resin sheet according to the present invention, in the sealing method of the thermoplastic resin sheet which seals the earth using a sealing member on the thermoplastic resin sheet having a pocket, the sealing method of the thermoplastic resin sheet includes at least one groove portion having at least one groove portion formed with parallel grooves. And a sealing step by a second seal member formed so that the groove of the groove portion and the groove of the groove portion intersect with the groove of the groove portion of the first seal member, and the sealing step by the first and second seal members is It is characterized by being carried out at least once each.

또한 본 발명에서의 열가소성 수지시트의 시일장치는 평행인 홈이 형성된 홈부를 갖는 제1의 시일부재와 홈부의 홈이 상기한 제1의 시일부재의 홈부의 홈과 교차하도록 형성된 제2의 시일부재를 구비하고, 상기한 제1 및 제2의 시일부재가 적어도 1개이상 구비되어 있는 것을 특징으로 하고 있다.In addition, the sealing device of the thermoplastic resin sheet according to the present invention includes a first seal member having a groove portion having parallel grooves and a second seal member formed so that the grooves of the groove portions intersect the grooves of the groove portions of the first seal member. And at least one of the first and second seal members described above is provided.

제1 및 제2의 시일부재에는 시일로울 또는 시일판이 각각 선택적으로 사용된다.Seal rolls or seal plates are selectively used for the first and second seal members, respectively.

시일부재로서 시일로울을 사용하는 경우에는 제1의 시일부재로서의 제1의 시일로울이 평행인 홈이 형성된 홈부를 적어도 2개이상 갖고 또한 인접한 홈부의 홈이, 서로 대칭방향이 되도록 형성됨과 동시에 제2의 시일부재로서의 제2의 시일로울이 상기한 제1시일로울의 홈부와 동수의 홈부를 갖고, 또한 각 홈부의 홈이 대응하는 상기한 제1의 시일로울의 홈부의 홈과 대칭방향이 되도록 형성되는 것이 바람직하다.When the seal roll is used as the seal member, the first seal roll as the first seal member has at least two groove portions with parallel grooves formed therein, and the groove portions adjacent to each other are formed so as to be symmetrical with each other. The second seal roll as the second sealing member has the same number of grooves as the above-described groove portion of the first seal roll, and the grooves of each groove portion are symmetrical with the groove portions of the above-described groove portions of the first seal rolls. It is preferably formed.

이와 같이 시일로울의 인접한 홈부의 홈을 단순히 교차하는 방향으로 하지 않고 대칭방향으로 형성하는 것은 홈부의 한쪽방향에 형성된 홈에 의하여 열가소성 수지시트가 로울축 방향으로 변위할려고 하는 힘을 상쇄하여 대지를 곧바로 이동시키기 위한 것이다. 이런 경우 홈부의 개수는 2개이상이면 임의인 것이다.Thus, forming the grooves in the adjacent grooves of the seal roll in the symmetric direction instead of simply crossing the grooves cancels the force that the thermoplastic resin sheet tries to displace in the direction of the roll axis by the grooves formed in one direction of the grooves. It is to move. In this case, the number of grooves is arbitrary if two or more.

또한 인접한 홈부에서의 홈끼리의 교차각은 반듯이 직각일 필요는 없고 예각둔각등 임의이다.In addition, the crossing angle of the groove | channel in adjacent groove part does not necessarily need to be a right angle, and is arbitrary, such as an acute angle.

또한 제1의 시일로울을 홈이 해당로울의 전둘레면에 걸친 스파이럴모양의 홈으로서 형성되는 것으로 하고, 제2의 시일로울을 홈이 상기한 제1의 시일로울의 홈과 대칭방향으로 형성된 것으로 하여도 좋다.In addition, the first seal roll is a groove formed as a spiral-shaped groove over the entire circumference of the roll, and the second seal roll is formed in a symmetrical direction with the groove of the first seal roll described above. You may also do it.

또한, 시일부재로서 시일판을 사용하는 경우에는 제1의 시일부재로서의 제1의 시일판이 평행인 홈이 형성된 홈부를 적어도 2개이상 갖고 또한 인접한 홈부의 홈이 서로 교차하도록 형성됨과 동시에 상기한 제1의 시일판의 홈부와 동수의 홈부를 갖고 또한 각 홈부의 홈이 대응하는 상기한 제1의 시일판의 홈부의 홈과 교차하도록 형성된다.In the case of using the seal plate as the seal member, the first seal plate as the first seal member has at least two or more groove portions in which grooves are formed in parallel, and the grooves in the adjacent groove portions are formed to intersect with each other. The groove part of the seal plate of 1 is equal to the groove part, and the groove part of each groove part is formed so that it may cross | intersect the groove part of the said groove part of the said 1st seal plate correspondingly.

이런 경우, 열가소성 수지시트가 흐름방향에 대하여 직각방향으로 변위할 염려는 없기 때문에, 제1의 시일판의 홈부 및 홈과 제2의 시일판의 홈부 및 홈과의 형성방향 및 수지관계는 마름모눈모양의 시일이 형성되는 한 자유롭게 된다.In this case, since the thermoplastic resin sheet does not have to be displaced in a direction perpendicular to the flow direction, the formation direction and the resin relationship between the groove portion and the groove of the first seal plate and the groove portion and the groove of the second seal plate are rhombus. As long as the seal of the shape is formed, it is free.

또한 본 발명에서 사용되는 시트에는 두께의 엷은 필름도 포함한다.The sheet used in the present invention also includes a thin film of thickness.

이하 본 발명에 관한 열가소성 수지시트의 시일방법 및 그 장치의 최선행태로서의 제1 및 제2실시예를 도면을 참조하여 설명한다.EMBODIMENT OF THE INVENTION Hereinafter, the sealing method of the thermoplastic resin sheet concerning this invention, and the 1st and 2nd Example as an optimal state of the apparatus are demonstrated with reference to drawings.

As shown in FIG. 2, the first seal roll 12 has two groove portions 18A, 18B having parallel grooves 17A, 17B inclined on its outer circumferential surface, and adjacent groove portions 18A, Sloped grooves 17A and 17B of 18B are inclined grooves 17A and 17B of groove portions 18A and 18B as intermediate radiating surfaces between groove portions 18A and 18B. 1,2,3,4,5) They are formed symmetrically with respect to their rotational direction.

또한 제3도에 보여주는대로 제2의 시일로울(13)은 제1의 시일로울(12)이 홈부(18A),(18B)와 동수인 2개의 홈부(19A),(19B)를 갖고, 각 홈부(19A),(19B)의 경사진 홈(20A),(20B)이 대응하는 제1의 시일로울(12)의 홈부(18A),(18B)의 홈(17A),(17B)과 대칭방향에 형성된 것이다.Also, as shown in FIG. 3, the second seal roll 13 has two groove portions 19A and 19B in which the first seal roll 12 is equal to the groove portions 18A and 18B. The inclined grooves 20A, 20B of the grooves 19A, 19B are symmetrical with the grooves 17A, 17B of the groove portions 18A, 18B of the corresponding first seal roll 12. It is formed in the direction.

제4도에 보여주는대로 제1의 시일로울(12)의 홈부(18A)(다른쪽의 홈부 18B도 같음)에 형성된 홈(17A)은 그 홈 사이의 피치(P)를 0.8㎜로 하고 홈의 각도를 θ로 하고 또 홈의 깊이(D)를 0.4㎜로 한다.As shown in FIG. 4, the groove 17A formed in the groove portion 18A of the first seal roll 12 (the same as the other groove portion 18B) has a pitch P between the grooves of 0.8 mm. The angle is θ and the depth D of the groove is 0.4 mm.

또한 제2의 시일로울(13)의 홈부(19A),(19B)에 대하여도 제1의 시일로울(12)의 홈부(18A),(18B)와 같은 구성을 한다.The grooves 19A and 19B of the second seal roll 13 also have the same configuration as the grooves 18A and 18B of the first seal roll 12.

또한 시일상태를 안전하게 하기 위하여 제1 및 제2의 시일로울(12),(13)의 홈부(18A),(18B),(19A),(19B)의 경계는 각 포켓(21)사이에 위치시켜 포켓(21)에 걸리지 않게 한다.In addition, the boundary between the grooves 18A, 18B, 19A, and 19B of the first and second seal rolls 12 and 13 is located between the pockets 21 to secure the seal state. So as not to be caught in the pocket 21.

상기한 구성을 갖는 시일장치를 사용하여 다음과 같이 대지(15)를 열가소성 수지시트(22)에 시일한다.The mount 15 is sealed to the thermoplastic resin sheet 22 as follows using a sealing apparatus having the above-described configuration.

도시않은 성형드럼으로 포켓(21)이 형성된 열가소성 수지시트(22)는 시일받이로울(11)에 보내지고, 여기서 송출로울(16)에서 공급된 A1박의 대지(15)가 제1의 시일로울(12)에 의하여 시일된다. 이때의 시일조건은 시일온도가 160℃-190℃, 시일압력(선압)이 3-7㎏/㎝, 시일속도가 5-12m/분이다.The thermoplastic resin sheet 22 in which the pocket 21 is formed by a molding drum (not shown) is sent to the seal receiving bowl 11, where the sheet of A1 foil supplied from the feeding roller 16 is the first seal roller. It is sealed by (12). The sealing conditions at this time are 160 degreeC-190 degreeC, sealing pressure (linear pressure) 3-7 kg / cm, and sealing speed 5-12 m / min.

이러한 시일에서는 시트(22)에 시일된 대지(15)의 표면에는 홈(17A),(17B)사이에 위치하는 뫼(23A),(23B)의 부분이 각각 경사지게 평행인 선모양 시일이 되어 형성된다.In such a seal, the surface of the earth 15 sealed to the sheet 22 is formed by a line-shaped seal in which the portions of the grooves 23A and 23B located between the grooves 17A and 17B are inclined in parallel, respectively. do.

계속하여 열가소성 수지시트(22)는 제2의 시일로울(13)에 의하여 시일된다.Subsequently, the thermoplastic resin sheet 22 is sealed by the second seal roll 13.

이때에 시일조건은 제1의 시일로울(12)에 의한 시일조건과 같다.At this time, the sealing condition is the same as the sealing condition by the first seal roll 12.

이러한 시일에서 대지(15)의 표면에는 제1의 시일로울(12)에 의하여 이미 형성되어 있는 경사진 평행인 선모양시일로 겹쳐지도록 하여 홈(20A),(20B)사이에 위치하는 뫼(24A),(24B)의 부분이 각각 새로이 직교하는 경사진 평행선모양 시일로서 형성된다.In this seal, the surface of the earth 15 is overlapped with an inclined parallel line-shaped seal already formed by the first seal roll 12 so that the mew 24A is located between the grooves 20A and 20B. The portions of) and 24B are each formed as a new orthogonal inclined parallel line seal.

따라서 제1의 시일로울(12)에 의하여 형성된 선모양시일과 이러한 선모양 시일과 직교하도록 제2의 시일로울(13)에 의하여 형성된 선모양시일이 겹쳐져서 종전의 1개본의 시일로울에 의하여 형성된 마름모눈모양시일과 같은 형상의 시일을 얻을수 있게 된다. (제9도와 제10도)Accordingly, the linear seal formed by the first seal roll 12 and the linear seal formed by the second seal roll 13 are orthogonal to each other so as to be orthogonal to the linear seal, and thus formed by the previous seal roll. It is possible to obtain a seal having the same shape as a diamond-shaped seal. (Figure 9 and 10)

[실험예 1-3][Experimental Example 1-3]

상기한 실시예에서 시일폭 시일온도, 시일선압, 시일속도를 하기의 표-1에 보여주는대로 설정하여 실험예1-3에 관한 블리스터 성형품을 제조하였다.In the above embodiment, the seal width, the seal temperature, the seal line pressure, and the seal speed were set as shown in Table 1 below to prepare a blister molded article according to Experimental Example 1-3.

또한 각 실험예에서 사용한 구체적인 열가소성 수지시트(22) 대지(15)의 A1박등은 다음과 같다.In addition, A1 foil etc. of the specific thermoplastic resin sheet 22 earth 15 used by each experiment example are as follows.

각 실험예에서 얻어진 성형품에 대하여 대지(15)와 시트(22)와의 시일상태(먹어들음, 먹여들음불균형, 시일강도, 강도불균형) 핀홀 및 컬(Curling)상태를 측정, 평가한 결과를 다음 표-1에 보여준다.For the molded articles obtained in each experimental example, the seal state (feeding, feeding unbalance, seal strength, strength imbalance) between the ground 15 and the sheet 22 was measured and evaluated. Show at -1.

또한 시일상태의 먹여들음(bite)은, 목측으로 판정한 것이다. 핀홀(pinholes)은 성형품의 반대측에서 빛을 대어 목측으로 판정한 것이다.In addition, the bite of the seal state was determined by the neck side. Pinholes are determined by the neck side by applying light from the opposite side of the molded article.

컬상태는 성형품 1유닛에 대하여 시일에서 24시간후에 시트(22)의 이동방향에 따라 50㎜간격을 갖는 양끝부의 굽힘을 측정하고 양끝부의 굽힘을 합쳐 2로 나눈 것이다.The curl state is measured by bending the ends of the two ends having a 50 mm interval in accordance with the moving direction of the sheet 22 after 24 hours from the seal with respect to one unit of the molded article, and dividing the bending of both ends by two.

[비교예 1-5]Comparative Example 1-5

제18,19도에 보여주는대로 시일로울로서 그 표면에 마름모눈모양의 철모양부(56)가 형성된 1개분의 시일로울(55)을 사용하고 시일폭, 시일온도, 시일선압, 시일속도를 하기의 표-1에 보여주는듯이, 설정하여 비교예1-5에 관한 블리스터 성형품을 제조하였다.As shown in FIGS. 18 and 19, a seal roll 55 having a diamond-shaped iron portion 56 formed thereon as a seal roll, and the seal width, seal temperature, seal line pressure, and seal speed are shown below. As shown in Table-1, the blister molded article according to Comparative Example 1-5 was prepared by setting.

시일로울(55)의 철모양부(56)의 피치폭, 깊이등은 상기한 실시예의 홈(17A),(17B),(20A),(20B)의 경우와 같다.The pitch width, depth, and the like of the iron shaped portion 56 of the seal roll 55 are the same as those of the grooves 17A, 17B, 20A, and 20B of the above-described embodiment.

또한, 각 비교예에서 사용한 구체적인 열가소성 수지시트, 대지의 A1박등도 상기한 실험예와 같다.Moreover, the specific thermoplastic resin sheet used by each comparative example, A1 foil of earth, etc. are also the same as the above-mentioned experimental example.

각 비교예에서 얻어진 성형품에 대하여, 상기한 실험예와 같이 대지와 시트와의 시일상태(먹혀들음, 먹혀들음불균형, 시일강도, 강도불균형), 핀홀 및 컬상태를 측정, 평가한 결과를 하기의 표-1에 보여준다.For the molded articles obtained in each of the comparative examples, the result of measuring and evaluating the state of sealing between the earth and the sheet (sucking, feeding unbalance, seal strength, strength imbalance), pinholes and curls, as in the above-described experimental example, Shown in Table-1.

Figure kpo00001
Figure kpo00001

표1에 의하여 실험예1에 의하면 시일온도 및 시일선압이 낮은데도 불구하고, 얻어진 성형품에 대하여 먹혀들음, 먹혀들음불균형, 시일강도, 강도불균형에 관한 시일상태가 양호하고 핀홀도 없고 또한, 시일로부터 24시간후의 컬이 작은 것을 알수 있다.According to Experimental Example 1 according to Table 1, although the seal temperature and the seal linear pressure were low, the obtained seals had a good sealing condition with no pinholes, no pinholes, and no pinholes. The curl after 24 hours is small.

실험예2에 의하면, 실험예1에 비하여, 시일폭이 넓게 되어 있으나, 시일상태와 컬상태가 양호하고 또한 핀홀의 발생도 볼 수 없음을 알 수 있다.According to Experimental Example 2, although the seal width was wider than Experimental Example 1, it was found that the seal state and the curl state were good, and the occurrence of pinholes was not seen.

실험예3에 의하면 실험예1에 비하여 시일속도가 빨리되어 있으나 시일상태와 컬상태가 양호하고 또한 핀홀의 발생도 볼 수 없다.According to Experimental Example 3, the sealing speed is faster than that of Experimental Example 1, but the sealing and curling conditions are good, and no pinholes can be seen.

따라서 본 실시예에 의하면, 시일공정에서의 시일폭의 확대시일 온도의 저온화, 시일속도의 고속화 및 시일 압력의 저감화가 가능하게 되고, 이러한 시일조건에서 컬이 극히 적고 또한 핀홀이 없는 성형품을 얻을 수 있다.Therefore, according to the present embodiment, it is possible to lower the sealing temperature in the sealing process, lower the sealing temperature, increase the sealing speed, and reduce the sealing pressure, and obtain a molded article having very few curls and no pinhole under such sealing conditions. Can be.

또한 비교에1에 의하면, 실험예1과 같은 조건인데 종전의 시일로울(55)를 사용하고 있기 때문에 대지의 시트로의 먹혀들음이 불량인 것에 더하기, 시일강도가 낮은 것을 알 수 있다.In addition, according to the comparison 1, the same conditions as in Experimental Example 1, but because the conventional seal roll 55 is used, it can be seen that the sealing strength is low, in addition to the poor feeding into the sheet of the earth.

비교예2에 의하면 비교예1에 비하여 시일온도를 높히고 있음에도 불구하고, 먹혀들음 불균형이 생겨 시일강도가 컬상태가 악화한다.According to the comparative example 2, although the sealing temperature is raised compared with the comparative example 1, a feeding imbalance arises and seal strength worsens in a curl state.

비교예3에 의하면 비교예2와 비교하여 시일폭을 넓게함과 동시에 시일상태 전반에 대하여 특성이 악화하고 컬상태도 불량하게 된다.According to the comparative example 3, compared with the comparative example 2, while widening a seal width, the characteristic deteriorates over the whole sealing state, and the curl state is also bad.

비교예4에 의하면 비교예3과 비교하여 시일선압을 높혔는데도 불구하고, 시일상태 전반에 대하여 특성이 불량인 것에 더하기 핀홀이 생기고 컬상태도 불량하다.According to the comparative example 4, although the seal line pressure was raised compared with the comparative example 3, in addition to a bad characteristic with respect to the whole seal | sticker state, a pinhole arises and a curl state is also bad.

비교예5에 의하면 비교예4와 비교하여 시일폭을 좁게하였으나, 시일속도를 빨리되었음으로 시일상태 및 컬상태가 불량인 것에 더하기 핀홀도 생긴다.According to the comparative example 5, although the seal width was narrowed compared with the comparative example 4, since the sealing speed became fast, a seal hole and a curl state were bad, and a pinhole was also produced.

또한, 상기한 실시예에서는 제1과 제2의 시일로울(12),(13)의 외주면에 2개의 홈부(18A),(18B),(20A),(20B)를 마련하였으나 홈부의 개수는 임의이다 .In addition, in the above embodiment, two grooves 18A, 18B, 20A, and 20B are provided on the outer circumferential surfaces of the first and second seal rolls 12 and 13, but the number of grooves Is arbitrary.

예를 들어 제5도와 제6도에 보여주는대로 제1의 시일로울(31)에 서로 홈(32A),(32B),(32C)의 방향이 상이한 3개의 홈부(33A),(33B),(33C)를 마련하고 또한 제2의 시일로울(34)에도 제1의 시일로울(31)과는 홈(35A),(35B),(35C)의 방향이 상이한 3개의 홈부(36A),(36B),(36C)를 마련하도록 하여도 좋다.For example, as shown in FIG. 5 and FIG. 6, the first seal roll 31 has three groove portions 33A, 33B, and 33 different from each other in the directions of the grooves 32A, 32B, and 32C. 33C), and the second seal roll 34 also has three groove portions 36A, 36B different in the direction of the grooves 35A, 35B, 35C from the first seal roll 31. ) And 36C may be provided.

또한 상기한 실시예와는 달리, 시일로울에 복수의 홈부를 마련않고, 제1의 시일로울에는 그전 둘레면에 스파이럴모양의 홈을 형성하고, 제2의 시일로울에는 그 전체면에 제1의 시일로울의 홈과 대칭방향인 경사진 홈을 형성하여도 좋다.In addition, unlike the embodiment described above, a plurality of grooves are not provided in the seal roll, and a spiral-shaped groove is formed in the first seal roll in the circumferential surface thereof, and in the second seal roll, the first seal is formed in the entire surface thereof. An inclined groove that is symmetrical with the groove of the seal roll may be formed.

그러나 이런경우 시트의 적당한 뱀달림 방지수단을 강구할 필요가 있고, 상기한 실시예와 같이 가시일로울에 서로 대칭방향의 홈이 형성된 복수의 홈부를 마련하는 것이 바람직하다.In this case, however, it is necessary to find a suitable anti-snagging means of the sheet, and it is preferable to provide a plurality of grooves in which symmetrical grooves are formed in the visible mirror as in the above-described embodiment.

또한, 이상의 제1실시예에서는 제1의 시일로울에 형성된 홈과 제2의 시일로울에 형성된 홈과의 형성방향은 뱀달림 방지를 고려하여 대칭방향으로 형성하기로 하였으나, 뱀달림 방지수단을 별도로 마련하고 양홈을 단순히 대칭방향에 마련하여도 좋다.In addition, in the first embodiment, the direction in which the groove formed in the first seal roll and the groove formed in the second seal roll is formed in the symmetric direction in consideration of the anti-snake, but the anti-snake means is separately provided. And both grooves may be simply provided in a symmetrical direction.

또한 제7도 및 제8도에 보여주는대로 제1의 시일로울(41)에는 그 전체면에 로울측에 평행으로 복수의 홈(42)을 마련함과 동시에 제2의 시일로울(43)에는 그 전체면에 로울축에 수직으로 복수의 홈(44)을 마련토록 하여도 좋다.7 and 8, the first seal roll 41 is provided with a plurality of grooves 42 on its entire surface in parallel to the roll side, and at the same time, the second seal roll 43 has its entirety. A plurality of grooves 44 may be provided on the surface perpendicular to the roll axis.

이러한 구성인 경우, 제1의 시일로울(41)과 제2의 시일로울(43)과의 순번을 대칭으로 하고 제2의 시일로울(43)의 쪽을 먼저 배치할수도 있다.In such a configuration, the order of the first seal roll 41 and the second seal roll 43 may be symmetrical, and the second seal roll 43 may be arranged first.

이상 설명한 제1의 실시예에 의하면, 저온, 고속의 시일조건이라도 양호한 시일상태를 갖는 성형품이 얻어진다.According to the first embodiment described above, a molded article having a good sealing state can be obtained even at low temperature and high speed sealing conditions.
